Post-frontal boundary - big changes have swung through central Mississippi; in many areas, temperatures were 40 - 50° below where they were on Saturday though much of the day.
The cold weather will settle in overnight tonight as temperatures drop into the middle and upper 20s by early Monday morning. This, in of itself, wouldn't be the coldest air mass we've seen in our area this year. The biggest difference is the winds.
Usually, at night, wind would slacken off - not the case tonight nor Monday night as our big dome of high pressure begins to move into the area. The gradient between the arctic high and the exiting storm system will keep winds quite brisk, about 10 - 20 mph; this will push wind chills in the teens and, for some in the Delta, single digits.
Tonight is a 3 P's night; check on sensitive PEOPLE, make sure the PETS are warm and if you have any PLANTS, you may want to make sure they are brought inside or covered up.
Wind chills on Tuesday morning won't be as brutal, but still cold enough, in the upper teens and lower 20s. Expect a gradual warming trend through Wednesday as highs rebound back to the lower 60s ahead of our next cold front.
